Codeigniter, Undefined variable without $data

Question

salam, I'm having a problem with a variable that is undefined in view. I don't use a $data variable in the controller before. after I use the $data, it still remains doesn't appear in my view (called dashboard). Can someone help me to solve this code?

I'm sorry, I know there are questions like this before. but I want to know mine, what is the problem, besides my code in another file are fine

home.php as controller

class Home extends CI_Controller{
public function __construct(){
    parent::__construct();
    $this->loginstatus->check_login();
    $this->load->library('template');
    $this->load->model('day_off_model');
}

public function index(){
    redirect('home/info');
}

public function info(){
    $data = array();
    $data['ym'] = date('Y-m');
    $this->template->display('information/dashboard');

    date_default_timezone_set('Asia/Tokyo');

    //$data['harian'] = 'a';
    // Get prev & next month
    if (isset($_GET['ym'])) {
        $ym = $_GET['ym'];
    } else {
        // Bulan ini
        $ym = date('Y-m');
    }
    //echo $ym;

    // Check format
    $timestamp = strtotime($ym . '-01');
    if ($timestamp === false) {
        $timestamp = time();
    }

    // Today
    $today = date('Y-m-j', time());

    // H3 title
    $html_title = date('m Y', $timestamp);

    $parts =  explode(' ',$html_title);
    $date   = $parts[0].' '.$parts[1];

    // return $date;
    // print_r($html_title);
    // die();

    $html_title=$this->tanggal->tanggal_indo_month_yeartext($date);

    // print_r($html_title);
    // die();

    // link prev next     mktime(hour,minute,second,month,day,year)
    $prev = date('Y-m', mktime(0, 0, 0, date('m', $timestamp)-1, 1, date('Y', $timestamp)));
    $next = date('Y-m', mktime(0, 0, 0, date('m', $timestamp)+1, 1, date('Y', $timestamp)));

    // Jumlah hari seblan
    $day_count = date('t', $timestamp);

    // 0:Minggu 1:Senin 2:Selasa ...
    $str = date('w', mktime(0, 0, 0, date('m', $timestamp), 1, date('Y', $timestamp)));
    //$str = date('w', mktime(0, 0, 0, date('m', $timestamp), 1, date('Y', $timestamp))); //senin, selasa, rabu

    // Create Calendar
    $weeks = array();
    $week = '';

    // cell dengan tabel kalender
    $week .= str_repeat('<td></td>', $str);
    //$week .= str_repeat('<td></td>', $str-1);

    for ( $day = 1; $day <= $day_count; $day++, $str++) {

        $date = $ym.'-'.$day;
        $exist = $this->day_off_model->get_all(false)->num_rows();
        // print_r($exist);
        // die();
        if ($today == $date) {
            $week .= '<td class="today">'.$day;
        } else {
            $week .= '<td>'.$day;
        }
        $week .= '</td>';

        // End of the week OR End of the month
        if ($str % 7 == 6 || $day == $day_count) {
        //if ($str % 7 == 0 || $day == $day_count) {
            if($day == $day_count) {
                // empty cell
                $week .= str_repeat('<td class="column_custom"></td>', 6 - ($str % 7));
                //$week .= str_repeat('<td></td>', 7 - ($str % 7));
            }

            $weeks[] = '<tr>'.$week.'</tr>';

            // weeks
            $week = '';
        }
    }
    //redirect('home/info');
}

dashboard.php as view

<?php if($this->session->userdata('user_type_id')==TRUE){?>
<div class="row">

        </tr>
        <?php
            foreach ($weeks as $week) {
                echo $week;
            }   
        ?>
    </table>
</div>
</div>
<?php }
else{?>

<?php }?>

I'm curious about $ym too. variable $prev, $html_title and $next are not identified. Should I pass this code?

thank you

What do your routes look like? Instead of redirecting, you should load a view and pass the variables in there. Have a look at this documentation for dynamically adding data to a view: codeigniter.com/user_guide/general/… — Timothy Fisher

I'm using home as default $route['default_controller'] = "home"; $route['404_override'] = ''; $route['translate_url_dashes'] = true; — Rifqi Ramadhani

So it looks like from your info method you need to load a view instead of redirecting. Like this: $this->load->view('home/info', $data);. You need to group up all of the data you wish to pass to the view into a single array. Also, in your index method instead of redirecting, maybe just do return $this->info(); — Timothy Fisher

it occurs an error An Error Was Encountered Unable to load the requested file: home/info.php — Rifqi Ramadhani

Make sure that your view file is in the correct directory: application/views/home/info.php. You would create a folder for your class, and a view file for each method. — Timothy Fisher

I think you're looking for this sort of structure:

class Home extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        // load other stuff
    }

    public function index()
    {
        $this->info();
    }

    public function info()
    {
        $data = [];

        // group all data you wish to pass to the view inside the $data array in this format:
        // $data[<variableName>] = <variableValue>

        $this->load->view('myView', $data);
    }
}

All of your variables that you want available inside the view need to be defined as a key in the array that you pass, in this case $data:

$data['myVar'] = 'myValue'

Will correspond to the following in the view:

var_dump($myVar); // result: myValue

You can do the same with arrays that you want to pass:

$data['myArray'] = [1, 2, 3, 4];

And access it in the view as follows:

var_dump($myArray); // result: [1, 2, 3, 4]

In the Controller Change these lines

public function info(){
    $data = array();
    $data['ym'] = date('Y-m');
    $this->template->display('information/dashboard');

To

public function info(){
    $data['ym'] = date('Y-m');
    $this->template->display('information/dashboard', $data);

In the view file, you can echo the ym's value like this;

echo $ym;
